Samsung s25 - HEVC recordings saturated colors

[MarcusDeMan]

Hi all,

I've recently upgraded my phone to the Samsung s25 that supports HEVC recording.

When viewing the video with VLC the colors appear to be ok as captured.

But when I import the same video into Avidemux the colors are all very saturated.

Does this happen because of the video decoder (Lavcodec RGB)? If so, how can I change that?

If not, what can I do to make the colors appear the same as captured on my phone or when viewing with VLC?

Presumably due to HDR -> SDR conversion, given the source video has color depth > 8 bit. There are various HDR tone mapping algorithms in the Video menu available, none perfect and all unaccelerated (performed on the CPU). Please try playing with settings to reduce saturation.

Does this happen because of the video decoder (Lavcodec RGB)?

Not in this case.

Unrelated: please consider switching from unaccelerated fallback "Qt" video display, indicated by the "RGB" label (it looks like you are using a pretty old Avidemux build as current 2.8.2 builds display information about decoder and display in the status bar) to a better option (all other options are better). The best and also the default video display in Avidemux on Windows is "DXVA2" (actually DirectX).
